There are a number of solutions that you can try to fix "This feature is unavailable. You do not have the required account privileges." error when playing NBA 2K21 on the PS4. Here are the things that you must do:

   Unlike their PC counterparts, PS4 users will have to ensure that they have an active PlayStation Plus subscription in order play any online mode of NBA 2K21. So, the first thing that you want to do is to check if your PlayStation Plus account is still active or not. If you PS Plus account has expired, you’ll need to renew your membership in order to play online.

2. Double check if a child account is signed in.

   If you have an active PlayStation Plus account but you are still unable to play NBA 2K21 online, the cause of the “feature is unavailable… required account privileges” error might be due to a signed in child account in your PS4. To fix the problem, here’s what you must do:-On your controller, press and hold the PlayStation button.-Select Power.-Select Switch User.-You’ll see a list of accounts on your PlayStation 4, with notes on which accounts are logged in. Select any account that is logged in but isn’t the account you’re trying to use.-At the home screen of that account, hold down the PlayStation button and select Power > Log Out of PS4.-Repeat the steps above if needed to ensure that only your account (adult account) remains logged in.

3. Update NBA 2K21.

   If you are still getting “This feature is unavailable. You do not have the required account privileges.” error even after doing the first two solutions above, other causes be to blame.
